MMR Small Block Street Killer Krate

This is the small block version of our tried and true Street Killer Krate. This 440 HP 500ft/lb small block is well mannered enough to drive across country yet can be obnoxious enough to get the attention of the local Sherriff you want to misbehave! We start with 360 block and do our usually race prep. Sonic check, align hone, parallel deck, bore and hone with deck plates to ensure a precision machined, durable short block. We then install one of our pump gas, Street 4” stroker rotating assemblies. This cast crank kit is cost effective and is practically bulletproof under 5500 RPM’s. The forged I beam is light weight and helps these engines rev faster than a 340! Since this is a “Street” engine we design the cam to be all done by 5500 RPM so it works great with 3.23 gears. The 4” stroke in more than a 440, these engine make AWESOME torque yet fit where are 318 might have been, can you say sleeper? We then finish filling the short block with Comp Cams timing chain, camshaft and lifters. A Melling oil pump keeps everything lubricated and a Mopar Performance distributor drive and timing chain tensioner keeps everything timed properly. A new oil pan and pick up complete the bottom end. All assembly information is recorded on a build sheet by one of our experienced engine assemblers. Anyone who assembles an engine here @ Muscle Motors has over 20 years of experience!!
